Windows 7 I've had great success using a RRAS server behind NAT devices and also the Windows 7 client behind a NAT device without much problem. Why they couldn't do this with XP is beyond me. I simply can't use the RRAS server behind a NAT device for L2TP IPSec remote access Windows XP clients. Tried this fix for XP SP3 clients and does not work for my RRAS Server behind NAT router.

I simply can’t use the RRAS server behind a NAT device for L2TP IPSec remote access Windows XP clients.

Great blog, by changing the regedit I could archive L2TP VPN connection between servers.
